Error Report Check

The Output/*_ErrReport.txt files are a very compact source of information. Please check there the event size (among 1k and 2k words), trigger rate (80 Hz for 3/4 trigger muons on Earth), track reconstruction rate (~50 Hz for muons 3/4 trigger), presence of errors (pay attention: one ladder T0-TDR18, may give many error. This is known!).

Data Quality Check

You can open the histogram monitoring files *_hmon.root with the MonitorUI program from everywhere. A typical example of usage is:

MonitorUI Output/0092716_1281323720_hmon.root

From the available histos you can choose:

  • Tracker data quality parameters: ladder average size, signal, tracker size, crates single sizes
  • Data taking quality: distribution inter-event
  • Ladder-by-ladder informations: signal, cluster size, seed occupancy, size
  • Reconstruction parameters: number of cluster, hits and tracks versus event number, rigidity, chisquared, eccetera
